Yep. No really big surprises but Nintendo is certainly picking up some good 3rd party support here.

What do the numbers underneath (2x, 4x, 8x) mean? Do you know? 

Just found out they give you the option to play 1st or 3rd person.
Makes me super happy, as I immensely prefer 3rd person. Definitely gonna get this.

It's a partial image of the floor plan those numbers are the amount of playable units what ever section of E3 it's showing has.

So how big is this game? I'm guessing it isn't nearly as popular as Overwatch but it probably can be a nice addition to the Switch.

Never heard about this game =p

It's possible but for online competition it will create lag. 

Well it's a poor man Overwatch. Only popular on Steam. It's quite popular actually but  it came after Overwatch recent popularity and it's hard for them to compete directly. 

In the same way that Overwatch was meant to be like Team Fortress (2)? Sure. It's a team based shooter with different classes/heroes/whatever that have different weapons and skills. These have been around a rather long time.

You some kind of comedian?
